[PATCH 3/3] phy: marvell: cp110: update mode parameter for pcie power on calls

[Baruch Siach]

From: Igal Liberman <igall at marvell.com>

It helps ATF to determine who called power on function (U-boot/Linux).

The corresponding ATF code was added in this commit:

  mvebu: cp110: avoid pcie power on/off sequence when called from Linux
